12-12V Voltage Stabilizer for continuous use at 3A.

product fit onto a ‘Click ‘n’ fit’ mounting clip which is fixed in three points allowing it to be mounted on uneven surfaces. It is easy to fit the clip into awkward places, then simply click the unit into position. A red LED indicates when there is output from the converter. This gives reassurance to the installation engineer and speeds fault finding.


Input voltage range 12Vdc, 24Vdc and 48Vdc +/- 30%
Output voltage 13.6Vdc or 27.2Vdc +15% -20% at extremes of temperature, load, input tolerance, etc.
Intermittent output power Continuous rating +25%, taken for a maximum f 2 minutes followed by 8 minutes rest.
Transient voltage protection Meets !SO7637-2 International standard for 24Vdc commercial vehicles
